Currently when an error occurs when calling devm_gpiod_get_optional or
calling gpiod_to_irq it causes an uninitialized error return in variable
'error' to be returned. Fix this by ensuring the error variable is set
from da8xx_ohci->oc_gpio and oc_irq.
Thanks to Dan Carpenter for spotting the uninitialized error in the
gpiod_to_irq failure case.
Addresses-Coverity: ("Uninitialized scalar variable")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
